MassGIS Data - LiDAR Terrain Data Index

July 2016

Overview

The LiDAR Terrain Data Index serves as a reference for downloading and ordering the LiDAR Terrain Data layers, which are organized into multiple project areas. This index dataset was created by MassGIS by merging shapefiles provided by each vendor as part of its complete LiDAR data delivery. MassGIS added the fields TILENAME (identifies the DEM and LAS files), AREA_NAME (the project area to which it belongs), URL (Web link to download digital elevation model (DEM) images), and ARCHIVED ('NO' = the most current data; 'YES' = older areas superceded by more current data). Note that tile sizes differ among the project areas, and some project areas overlap.

The layer is named LIDARINDEX_POLY.

See the overview Index Mapfile size 1MB based on this layer that displays all LiDAR project areas.

(Links to detailed index maps of each project area are found on each DEM download page; links to these pages appear on the main LiDAR Terrain Data page).

Maintenance

MassGIS maintains this layer and will update it should new LiDAR data be acquired.
